Plant Lust- 8 Must Haves

Plant Lust

According to Urban Dictionary, Plant Lust is defined as an uncontrolled desire or craving for any member of the kingdom Plantae. Yes, I just added that to the Urban dictionary as it is a well known term to plant addicts and I fit right into this category. Plant lust or envy is a condition with no cure or treatment. A craving or appetite for unusual plants is a common condition in garden circles and you learn to live with it. See what is on my current list.

Kingdom Plantae Wish List

I have a running list of plant acquisitions in the Kingdom Plantae pegged on my bulletin board that I “must” have. Understand, that I don’t “need” any of these. I need more plants like my dog needs more toys! I compare it to clothes shopping when you are not looking for anything in particular, and then spot something so perfect that from that moment on, you can’t do without.  When I visit different gardens and see something irresistible, I whip out my iphone, take a picture and look for the name tag. That happened recently when I visited Longwood Gardens in Kennett Square, PA, and my plant envy list just got longer. Here are a few things that I will be looking for next year, either seeds or plants, anyway that I can get them!

Pennisetum 'Feathertop'

Pennisetum ‘Feathertop’

1. Pennisetum villosum ‘Feathertop’– I am not a huge grass fan, but I definitely have some favorites that I use at many of my landscape jobs. Hakonechloa or Japanese Forest Grass, pictured below, is my absolute favorite grass for shade. But I am open to suggestions for new favorites.

So when I saw this Pennisetum ‘Feathertop’, I fell in love. Yes, it is an annual for me because it is hardy in zone 8 to 10. And yes, it looks like it could seed in after reading the reviews- meaning coming up everywhere. But with its pretty, white, bottlebrush plumes, perfect for cut flowers, these dramatic plumes contrast with all kinds of perennials – kind of how a pretty scarf can ramp up your outfit. This valuable attribute helped give Feathertop the Award of Garden Merit from the Royal Horticultural Society in 2002.

2. Ammi majus or Bishops Weed- An annual that looks like Queen Anne’s Lace on steroids. Instead of a flat umbel profile, the flower is dome-shaped, with beautiful frilly fern-like foliage. This plant also can seed in, but that’s quite all right. I can deal with it. I see this as a great filler and valuable addition in cut flower arrangements.

3. Celosia argentea ‘Sylphid’

What can I say about green flowers? I am a sucker for them every time. And when I spotted this Sylphid Plume Celosia, it was love at first sight. Graceful greenish-yellow feathery plumes sit on tall straight stems.  The perfect color to set off vibrant colors in your garden or bouquet.

4. Flashpoint Lily

Flashpoint is a Orienpet Lily (cross between an Oriental and Trumpet) which is an explosion of color, red and cream outfacing blooms. I didn’t see these at Longwood, but love this combination so much, I am going to duplicate it in my garden. Similar to a ‘Stargazer’ lily but with a lot more substance and staying power. Fragrant too!

5. Dahlia ‘Pam Howden’

Dahlias are definitely my weakness. Big, blowsy, colorful blooms that arrange beautifully and draw pollinators. What’s not to like? Pam Howden, a ‘waterlily’ type, is one I spotted and will be planting next year. Loaded with blooms, I admired another dahlia, pictured below, Starfire.

6. Hibiscus ‘Fifth Dimension’

Hibiscus was definitely not on my radar when I went to Longwood, but this one practically jumped up and hit me – Fifth Dimension. Looking the flower up on-line, I discovered that when the bloom first starts to open,  it is orange with a silvery contrasting center. As the day progresses, the orange changes to yellow. I caught this bloom in the yellow stage. Go to Longwood Gardens Blog  to see a time-lapse video of the transformation, like a psychedelic experience!

7. Gomphrena ‘Fireworks’

I admit I have grown this one before and loved it. But after spotting it in the Longwood beds, I need to add this to my permanent list of annuals for yearly planting.  Flowering all season long with straw textured globes, the ends of the petals are topped with yellow stars. I grow these from seed as I have never seen the transplants available in the spring.

8. Lisianthus or Eustoma

Commonly known as Prairie Gentian, Lisianthus plants are herbaceous annuals which have bluish-green, slightly succulent leaves and a large rose-like flowers growing on the long straight stems. Frequently seen as cut flowers at the florist, you can grow these in your garden if you can find the transplants in the spring as the seeds are very difficult and slow to germinate. Preferring cooler temperatures would limit this flower for me, but I would like to give it a try. Great as a long-lasting cut flower and I know this will be hard to find.

    Lisianthus are wonderful, I agree! We can get plants from the Amish nurseries in the spring, here in St. Mary’s county, MD. They are long lasting, as you said. I’ve seen white, pink, or the beautiful blue you showed.


  4. Pat Webster says:

    Thanks for the reminder about gomphrena, Claire. I grew it one year some time ago, forgot about it entirely. ‘Firecracker’ is now on my list for next year. I know exactly where to put it. And isn’t that one of the great things about visiting a good garden… seeing new plants, plants you’ve forgotten about, or plant combinations that you hadn’t thought of. Glad Longwood was on your list!
