Snapdragon Potomac 3-4
Potomac is more tolerant of heat than some series, making it a good choice for the main season. It likes long days and lots of light. This would be your best choice for summer planted snaps for fall bloom, as well.
Several colors out of stock and we are seeking a replacement series with better availability. Feel free to make suggestions!
Order 7 or more weeks in advance of desired ship date.
Grown in a 216 cell tray, billed as 210

About Tray Sizes
210 and 125 cell trays are full-sized trays, and three of these will fit in a shipping box.
50 cell trays are half-sized trays (unless otherwise noted) and two of these are the equivelent of one full sized tray. Six of these will fit in a shipping box.
18 and 32 cell trays are full sized trays specifically for our vernalized perennials. These have their own set of shipping rules (find details HERE) and cannot be combined with items grown in 210, 125, or 50 cell trays.

| Temperature Range |
Snapdragons like it cold, especially when young. Short drops to 20F or colder are tolerated well.
|
| Spacing |
Plant in clusters of 2-3 seedlings, with 6" spacing. Plugs are multi-seeded with this in mind.
|
| Soil Preference |
Well drained, generally fertile soil.
|
| Day Length |
Facultative long day
|
| Pinching |
Pinching will produces more, but smaller stems per plant. I prefer to not pinch, resulting in taller stems with larger flowers. Use a wider spacing when pinching.
|
| When to Plant |
In autumn, plant 3-4 weeks before first frost. In spring plant 3-4 weeks before last frost. These cold hardy plants prefer frosty conditions to hot conditions. Plant at the same time as Stock and Campanula.
|
| Harvesting |
Harvest when 1/3 to 1/2 of the buds are open.
|
| Post Harvest Care |
Harvest into a holding solution. Snapdragons are moderately sensitive to ethylene.
|
| Diseases / Insects |
Generally easy growing. Rust is an issue in some environments. Harlequin bugs love snapdragons in summer.
|
| Bailey's Notes |
When planted in fall or late winter, snapdragons will reach 3-4' easily. Different series bloom at different times and you can extend your harvest window by planting several series at the same time.
