Ammobium
Winged Everlasting is quite an old fashioned cut flower that can be used fresh or dried. Although it's technically a tender perennial in zones 9 and 10, it can be grown as an annual across much of the country. Plant in light, well drained soil in a sunny location for best results. Treat it similarly to helichrysum; it's half-hardy and can tolerate some cooler temperatures but don't plant it too early. Harvest before the yellow centers are showing if you want to dry it.
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.

| Common Name | Ammobium, Winged Everlasting |
| Genus | Ammobium |
| Species | A. alatum (grandiflorum) |
| Family | Asteraceae |
| Life Cycle | Annual (Perennial in zones 9-10) |
| Format | Plugs |
| Plug Care | Harden off and plant immediately after arrival to prevent plugs from becoming rootbound. Avoid excessive root disturbance during transplanting. Do not overwater if holding in the plug trays for any period of time - Ammobium is prone to root rot in overly saturated conditions. |
| Netting / Staking | Not typically necessary, but light support such as one layer of trellis can be beneficial in windy areas. |
| Temperature Range | These plants are sensitive to frost and freezing and thrive with warm days and cool nights. They will grow well in much of the US as an annual and will only overwinter in Zones 9 or higher. |
| Spacing | Space 9-12 inches apart to allow for proper airflow between plants which will help minimize disease risk. |
| Soil Preference | Well-drained, sandy, or loamy soil with a slightly acidic pH (5.5-6.5). Enrich beds with compost before planting. Avoid over-watering; well drained soil is key to avoid root rot. |
| Day Length | Day neutral, likely flowers better under long days; needs full sun to thrive. |
| Pinching | Pinching is not necessary, as stems rise from a low rosette of leaves (similarly to statice). |
| When to Plant | Plant in the spring, after all threat of frost has passed. |
| Harvesting | Expect approximately 10 stems per plant - harvest when the flowers are half open, but before the yellow centers are showing. Flowers will continue to open both in the vase if used fresh, or as they dry. It takes 70-80 days from planting to flower. |
| Post Harvest Care | If being used fresh, cut stems should immediately be placed into cool water (strip lower leaves off) and kept somewhere cool and out of the sun to hydrate. Expect a vase life of 7-10 days - the use of a floral conditioner is not absolutely necessary but may help to maximize vase life. To dry, harvest at the same time (before the yellow centers are showing) and simply hang upside-down to dry. |
| Diseases / Insects | Generally pest resistant - pollinators love the flowers if left to fully open in the field. Avoid overhead watering and provide adequate space to allow for airflow between plants to minimize risk of disease. Ammobium are native to Australia and prefer a more arid climate - they may suffer from long bouts of high humidity and moisture. |

If you are looking for a fun, whimsical new addition to your cut flower production - give these guys a try. The clusters of small daisy like flowers and unique ribbed or winged stems are really quite cute. |
