what do arborvitae seeds look like

Arborvitae, those beloved evergreen shrubs and trees gracing many landscapes, reproduce through seeds housed within their distinctive cones. Understanding what these seeds look like can be helpful for identification, propagation, and appreciating the life cycle of these hardy plants. This guide will delve into the appearance of arborvitae seeds, showing you how to identify them and what to expect.

Identifying Arborvitae Cones and Seeds

Arborvitae seeds aren't easily visible like some other plant seeds. They're nestled within woody cones that develop on mature plants. These cones, rather than the seeds themselves, are the first clue in identification.

Cone Characteristics:

Size and Shape: Arborvitae cones are small, typically ranging from 0.5 to 1 inch long. They're oval or oblong in shape, sometimes slightly elongated.
Color: Young cones are green, gradually turning brown as they mature and dry. The mature, woody cones are usually a reddish-brown or dark brown.
Texture: The cones have a slightly scaly texture, with overlapping scales covering the seeds. These scales are what protect the seeds throughout the winter.
Location: Cones are usually found at the tips of branches, often in clusters.

Seed Appearance:

Once the mature cone opens (usually in late winter or early spring), you'll find the seeds nestled within the cone scales. Individual arborvitae seeds are:

Small: Tiny, usually only a few millimeters in length.
Flattened: They have a somewhat flattened, winged shape. This wing aids in wind dispersal.
Color: Typically light brown or tan in color.
Texture: The seeds themselves have a smooth to slightly rough texture.

How to Find and Collect Arborvitae Seeds

Collecting arborvitae seeds requires patience and a keen eye. Here’s a step-by-step guide:

Identify Mature Cones: Look for brown, woody cones on mature arborvitae plants.
Timing is Key: The best time to collect seeds is late winter or early spring after the cones have fully dried and opened.
Gentle Collection: Carefully collect the cones by hand, avoiding damaging the branches.
Seed Extraction: Once collected, place the cones in a dry, well-ventilated area to allow them to open completely. Gently rub or shake the cones to release the seeds.
Cleaning and Storage: You might need to sift the seeds to remove any debris. Store the cleaned seeds in a cool, dry place in an airtight container until ready for planting.

What to Look For: Variations in Seed Appearance

While the general description above applies to most arborvitae species, there can be subtle variations in seed size, shape, and color depending on the specific cultivar. These variations are usually minor and won't significantly impact identification. If you're unsure about a specific species, consulting a botanical guide or plant identification expert can be helpful.

Frequently Asked Questions

Q: How long does it take for arborvitae seeds to germinate?

A: Germination can take several weeks to several months, depending on conditions such as temperature and moisture.

Q: What are the best conditions for growing arborvitae from seed?

A: Arborvitae seeds need consistently moist but well-drained soil. They thrive in partial shade to full sun.

Conclusion

Understanding what arborvitae seeds look like enhances appreciation of these evergreens’ life cycle. By recognizing the characteristics of both the cones and the seeds themselves, you can successfully collect and propagate these beautiful plants, adding to your landscape's beauty for years to come. Remember to always observe mature cones for the best chance of finding viable seeds and practice responsible harvesting.
