MrILoveTheAnts. I will compile a list later of what I am planting, but I am going to comment on a couple that you are growing that you had queeries about. You are doing excellent with the seed propogation. Now it sure is fun, eh? Good luck!!!!
<Cucumbers: My parents tell me I need to grow them on hills but I read they'll grow just as a tomato plant does when given a lattice.
I grow cucumbers on the ground, I don't bother with hills. I also grow cucumbers up trellises, like chicken wire strung along, they grow up and then hang over the other side, it works and it a great space saver.
<Mallow (rose pink): Meant for butterflies but it's resemblance to Rose of Sharon annoys me.
I grow a species of mallow, it is called Lavatera, it is beautiful, it is like a plant that grows about 2 feet tall, covered in beautiful deep pink flower that look like a hybiscus, much more pretty than the mallow, which has a nice flower, but the lavatera flower is larger and very beautifully deep in size, it self-seeds around here, comes up everywhere.
<Canterbury Bells: A biannual, I guess that means they don't bloom until the second year? But does it live past that?
A bieannial flower does not bloom the first year, the second year it has beautiful flowers, then this plant dies. It only lives for two seasons. Quite often with biennials though, the mother plant will set seeds and that carries on the species. This makes it appear like the mother plant never really dies. Biennials are wonderful to have. I have some and they have been here since I first planted them, over 15 years ago, they just keep going and going and going.
<Lavender: A different type and shade of blue then what I've already grown, I really want to make a boarder of alternating blues.
If you want some really pretty blue border plants, then think about Lobelia, Crystal Palace, an exciting colour of deep marine blue, cornflowers (dwarf) are pretty blue, ageratum, also comes in a pretty blue, good for borders. Google blue border plants, you will be surprised how many shades of blues there are (purple is called blue too, so that can be confusing).
<Coleus: Similar to a Hosta, but they're an annual with neat colored leaves. Basically the front garden gets almost no sunlight at all and everything we've planted there besides Hostas have died. Hopefully their flowers will be good for the bees.
Coleus do well in shaded areas, yes, hostas do love that cooler, low light condition too. If the hostas do well there, get some different cultivars, (or divide yours), they LOVE to be divided. I began with about 6 of the Royal Standard many years ago, now I have tons of hosta clumps everywhere, trust me, they love division. The Royal Standard (get that one if you can) has a beautiful white flower stalk that is EXTREMELY fragrant, smells alot like Gardenia, you would love it.
Have the best and most wonderful day, Cindi
