Mary Washington Asparagus (Heirloom)

Heirloom - 1900

The Mary and Martha Washington varieties of asparagus were developed around 1900 for greater disease resistance. From the 1930 DM Ferry seed catalog: “A vigorous growing and productive asparagus bred to resist the disease known as Asparagus Rust. Mary is a selection from Martha and is earlier and more robust.” Zone 3-8.

25 seeds



Asparagus officinalis

Germination: 10- 30 days

Germination Temperature: Optimum soil temperatures 70-80ºF

Seed Sowing Depth: 1/2" deep

Sowing Indoors: 12-14 weeks before last frost date. Soaking seeds in water overnight aids germination. Sow 2-3 seeds per cell/pot. Provide 70-85ºF soil temperature. Transplant after last frost in a 4-6” deep trench, 10-15" apart. Fill in the trench as the seedlings grow.

Sowing Outdoors: We recommend starting them indoors then transplanting out. Sow after last frost when soil temperature is over 70ºF. Sow 2-3 seeds every 10-15", thin to the strongest seedling. 

Harvest: Ready for harvest in 3-4 years, may selectively pick a few spears during the second-third year.

Tips:  Plant in fertile soil, amended with compost or well rotted manure and keep well watered. Keep weeded as asparagus doesn't compete well with weeds. Cut the fern- like growth to the ground when it becomes yellow and mulch with compost in fall.

m washington asparagus

I'm pretty sure I won't remember this past next week, but germination has always been good and asparagus is tough and yields are good.

Mary Washington Germination Review

The items arrived a little bit late because of the pandemic but they informed me of the delay and I was happy to wait. When I received the packet the seeds were healthy and I planted them. 100% germination rate. Thanks!

I was surprised and very

I was surprised and very pleased. Many of the seeds germinated and we have added them to our asparagus patch- man more than we expected

So far, so good!

These seeds sprouted very quickly! I planted four in each pot and, on average, two per pot sprouted (so far). I’ve had them outside since the weather got nice and they’ve held up very well to the wind and rain. I know it will be a while before I can eat them, so I can’t comment on taste yet, but I love them so far!


Surprised Me

I live in Central Florida, and thought I would give asparagus a try. Even if I got one fresh spear, I thought it would be worth it - bring back childhood memories from growing up in New England. Well, several of the plants I grew from seed over 5 years ago are still growing, and that's despite unavoidable neglect due to other demands on my time. Of the 2 varieties I've tried, the Mary Washington seems the toughest. I had no idea they would do that well here, under such harsh conditions. What a pleasant surprise.
