Fenton Friday: Lovely Lisianthus

This week the intense heat was back and we had hardly any rain. Now we are experiencing extremely poor air quality due to smoke blowing in from the Canadian wildfires. I'm praying for rains this weekend to clear out the air and for the gardens. The smoke haze cannot be good for our plants, which are already suffering greatly from the drought and record heat waves.

I cut blooms from the Dahlias and the Lisianthus (pictured above).

We weeded and watered a bit -- and picked a few Blackberries.

The Squash vines are flowering, so I expect to see them developing soon. The Eggplant and Tomatoes all have lots of blossoms on them. As soon as the temps go back to normal, we should have fruit development on both.

And speaking of Tomatoes, when I eft last week to go tour gardens in Buffalo, NY, there was one nice-sized tomato starting to ripen on the 'Fourth of July' plant. When I got back, it was gone -- not rotting on the ground nor bitten and left behind -- just gone. I suspect a hungry critter took it (maybe of the human kind?).

For the Pollinator Strip, we are still waiting on germination of the second batch of Nasturtium seeds and Celosia seeds that we planted last week. The Sunflowers and Marigolds are blooming well. The Zinnias still need a few weeks.

I finally got the Pepper seedlings planted! They are a sweet Cayenne variety and a 'Calabrian' one.

Everything else is coming along well. 

What are you growing and harvesting in your garden this week?

About Fenton Friday: Every Friday during the growing season, I'll be giving you an update on my community garden plot at the Fenton Street Community Garden just across the street from my house in zone 7 Mid-Atlantic MD/DC border. I'm plot #16. It is a 10 ft x 20 ft space and this is our 15th year in the garden. (It opened in May 2011.) See past posts about our edible garden by putting "Fenton"  into the Search box above (at the top, left on this blog).

Japanese Painted Fern Plant Profile

Japanese Painted Ferns Plant Profile

Japanese Painted Ferns (Athyrium niponicum) are perennial plants that highlight shady spots in the garden.

They are native to eastern Asia and are hardy to zones 3 to 8. The mature size is about 18 inches tall and wide.

The silvery highlights are the hallmark characteristic of this beautiful fern, but many cultivars also have red mid-ribs such as the award-winning cultivar ‘Pictum’. The cultivar 'Silver Falls' received the Royal Horticultural Society's Award of Garden Merit. Other popular cultivars include ‘Ghost’ and ‘Burgundy Lace’.

Japanese Painted Ferns make great garden accents and look good featured in containers.

Ferns do not have flowers so they do not attract pollinators, but they do assist wildlife by providing shelter and hiding spots.

They are deer-proof and have few pests. They thrive in consistently moist, well-draining, acidic soils with lightly dappled to full shade Japanese Painted  Ferns also appreciate a top-dressing of composted leaves.

These ferns are low-care. By late winter, you will want to cut them back though as they will look a bit ratty and tattered. Divide Japanese Painted Ferns in early spring just as new fiddleheads emerge or in the early fall. Do so every few years to maintain the plant’s vigor.

Fenton Friday: Going to Seed

This week the heat broke and we had lots of rain. That means the weeds are now rampant--especially the Morning Glory vines and Mulberry tree seedlings.

The Dill flowerheads are starting to dry on the plant. I cut them to save the seeds for culinary use (mainly making pickles) and sharing.

The Lettuces have bolted. In other words, they are going to flower and forming seeds. (See the Lettuce flowers in the photo above.) I'll cut the flowers to collect those seeds in another week or so.

We spread wood chips along the side path. It always looks so good right after we do that--wish it lasted longer--kind of like right after you vacuum a carpet.

For the Pollinator Strip, we soaked and planted a second batch of Nasturtium seeds to replace those that didn't germinate earlier. Then we planted Celosia 'Flamma Pink' seeds in a row behindthe Nasturtium.

Everything else is coming along well. I think in a few weeks we will be able to start harvesting Tomatoes, Okra, and Beans regularly.

I cut more Dahlia flowers and was able to snip a few early Lisianthus blooms to put in bud vases.

I still need to get those Pepper seedlings planted! At this rate, I may just gift them to another gardener.

Lamb’s Ear Plant Profile

Lamb’s Ear Plant Profile

The silver-gray basal foliage of Lamb’s Ears (Stachys byzantina) spreads along the ground by rhizomes and in early summer it sends up tall wands of purple flowers. Once the flowers are done, cut them back for a tidier garden look.

It is also known as Woolly Hedgenettle and Wooly Betony. It is native to Europe/Asia.

Lamb’s Ear is in the mint family (the square stem is a clue) and that is your indication also that this is a fast spreader when given the chance.

The soft, fuzzy leaves of this plant make it a favorite for children’s gardens and sensory learning.

That fuzziness also makes it unpalatable to deer and rabbits.

It prefers full sun and a well-draining soil. It can be planted on mild slopes and along sidewalk edges. A bit of foot traffic does not bother it and it bounces back well.

Lamb’s Ear is pretty shallow-rooted making it easy to dig and divide. Remove sections in spring or fall to fill in other areas or gift it to other gardeners.

It is considered semi-evergreen as the leaves can shrivel up and die back in cold winters. Remove any spent foliage in early spring to prepare the plant for the new growing season.

Lamb’s Ear does not tolerate wet conditions for long or high humidity. It is happiest when planted where it can get good air circulation around it. Once established, it is fairly drought-tolerant.

It attracts pollinators and is often planted in butterfly gardens. Lamb’s Ear is also used in xeriscaping and for fire-wise landscapes.

Lamb’s Ear – you can grow that!
