15 plants
If we had to choose plants to start a new garden with and was limited to 15 they would be: 1. Allium - I especially love the tall purple and white varieties, they look great poking through evergreen shrubs or contrasted with acid greens. We tend to leave these in the ground when they have died as we like the seed heads. This year we learn't from a that you may cut the foliage right back if it starts to look tatty and this won't harm the remaining flower spike. 2. Cosmos - My preference is bipinnatus over sulphureus as I prefer the wispy fern-like bright green foliage that accompanies the bright flowers. The foliage on the latter is much darker and more defined and in my view, less striking. 3. Dahlia - I have my Dad to thank for introducing me to these and I am so thankful. Excellent mixed with Cosmos and they flower around the same time - at least they do here in Zone 9. 4. Delphinium - I just really like these, I think they are underrated a
