Welcome to the course and I am glad you enjoyed the first section. Some people send one design a week and others send more. It is entirely up to you and your budget for flowers! Everyone is on different time scales, countries and seasons so it varies a lot. You should have access to reasonable flowers in Washington DC though I’d have thought?
I enjoy Photography as an art form. I've just spent the last 5 days photographing 7 gardens in the south of England including Munstead House, Kew, West Green, Mottisfont, Hilliers, Wisley and Hinton Ampner.
I am semi-retired, so have recently been able to devote more time to my photography. If you had asked me a year ago which were my favourite genres I would have said architecture, street photography and black and white.
That Heuchera's a pretty one - not a variety I've tried before. Does it have problems with vine weevil at all? Many Heuchera are very prone to this pest, especially in pots, but some are resistant. A great plant for pots because its foliage looks good pretty much all year. 'Sum and Substance' is and enormous Hosta - have you tried growing it in a pot? I never have just because it is so very big but I'm sure it would be fine in a big enough container. Hostas are classic plants for pots, something about being raised up enhances their shape - and of course it takes longer for the snails to reach them
Levisticum officinale looks to me like Ligularia stenocephala. Re Arunucus dioicus "It gets up to 150 cm high and it apparently is either a male or a female so it can‘t seed itself. but if you have both you'll have lots of babies!!! Tanacetum hedge!
Yes, fine, good plant selection, although i think that you are not able to use the taller perennials which make good structure plants especially with winter structure - I am thinking of all those North American prairie species like aster, eupatorium , solidago. I can imagine they need more heat to grow, they are not always successful in Ireland, let alone Iceland. Do you grow Delphiniums? They apparently grow very well in the Arctic.
Arunucus dioicus – So the plants that are either female or male, they are always a seeding type of perennial? About the structure plants all of those you mentioned have apparently been used in Iceland, Now I can start studying them as well
I understood the concept of symmetrical and asymmetrical planting and thinking of planting within a triangle much better in lesson 6 than I had in lesson 2. I have also started to write plant lists based on all the characteristics as you suggested in lesson 6 that I currently have in my garden. Much better than a label that I generally lose, and also very useful as an assessment for plants on my wish-list.
garden design is nothing to do with horticulture, but everything to do with people. Remember on this assignment you are DESIGNING your garden to be used. I know it’s tempting but the plants must come later
