Variety Info
Days to Maturity: 100-105 days
Family: Cucurbitaceae
Native: United States and Northern Mexico
Hardiness: Frost-sensitive annual
Exposure: Full sun
Plant Dimensions: Restricted vine about 45"
Variety Info: An acorn type squash with stark white skin and nearly white flesh. Fruits are 1-1.5 lbs on highly productive plants, typically producing three to four fruits per plant. Vines are compact and most fruit are found on the crown set. The crown set is the first female flowers produced before vining starts. This means that "Mashed Potatoes" produces more female flowers earlier in its growth stage. Fruits will still appear on longer vines, just less of them. Color of the fruits hold into late fall.
Attributes: Frost Sensitive
Sowing Info
When to Sow Outside: RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is 70°-85°F.
When to Start Inside: Not recommended except in very short growing seasons, 2 to 4 weeks before transplanting. Roots are sensitive to disturbance; sow in biodegradable pots that can be planted directly into the ground. Transplant when soil temperature is at least 60°F.
Sprouts in: 5- 10 days
Plant Seeds (Depth): 1/2"-1"
Space Seeds: 2-3 seeds per mound
Row Spacing: 3'-4'
Thinning: When 3 leaves, thin to 1 - 2 plants per mound
Growing Info
Harvesting: Harvest when the squash's rind is hard enough that you can't dent it with your fingernail and before first frost. Cut stem, (don't break it off) leaving 2" of stem attached, which keeps the squash whole, leaving no opening for infection. Though fruits are hard and may seem indestructible, treat them gently; bruising can spoil squash. Harvesting Blossoms: Look for pollen-producing flowers that have long stems and harvest just before use (fruit-producing flowers have a very small, developing squash at the base of the flower and shorter stems).
Special Care: To help protect plants against common pests like squash vine borer and cucumber beetles, use floating row covers, and remove covers when plants begin flowering. To further protect against vine borers, you can also cover the base of the stems near the ground with mulch, foil, or fabric material, as the base of the stem is where insect eggs are laid. Squash plants are susceptible to fungal disease, too, so make sure plants have ample space for air circulation. Sowing pollinator-attracting plants near squash can assist in proper pollination, resulting in a bigger harvest and well-shaped fruit.
- Marina M.Verified BuyerRated 1 out of 5 starsJul 30, 2026None of the seeds germinated for me.
I am a regular buyer of this seed company. Sadly, not one single seed germinated for me. I'm at a loss here. I have a beautiful, vibrant garden and have several squash plants growing. I tried in the ground, in a raised bed. I tried a few weeks apart. Nothing. I'm reading the wonderful comments and have serious FOMO. I have 2 more packets in my cart. Last chance. I'm in Southern California. Los Angeles County.

- Ruxandra N. (.Verified ReviewerRated 5 out of 5 starsMay 31, 2026My all time favorite squash
We love squash. Our garden is full of all varieties from three kinds of zucchini to heirloom pumpkins. We planted these last year and I mostly neglected them and we still got a dozen squash from about 3 plants. This year I'm going to baby them because it was the most delicious squash I've had. Tastes just like mashed potatoes and we ate them with butter, salt, and pepper. Perfect addition to any meal!

- Erica M.MI, United StatesVerified BuyerRated 5 out of 5 starsSep 17, 2026Cute! These are just so cute!!!
Zone 6B backyard/raised bed gardener here, pretty new to the gardening scene. I was a little chaotic in my planting this year and direct sowed a few weeks after memorial day. They required very little space to grow, and flowed off the edge of my garden bed where I had some bare space. Read- my gardening efforts are "if it lives, great, if it doesn't make it, I wont even notice" kind of thing. These little things were all for it. Germination went well, the plants flourished, and they took up very little space. I now have the CUTEST little white squash ready for picking, each plant was pretty small in comparison to the amount of little treats it gave me.
These were my happy little surprise this year and I will definitely keep growing these.

I second all the other 5 Star reviews. It's way better than original mashed potatoes. It takes very little butter and salt to get an amazing dish. I only have 1 plant, but so far it's pumped out 6 babies. Plan to sow many more next year! Thank you BI for offering this one!

- Louise D.Verified BuyerRated 5 out of 5 starsJul 23, 2026Unbelievably creamy squash
This squash blew my freakin' mind. I grew two plants and just picked two squash (in July!). Roasted them, mashed them with salt and butter, and had them with homemade mashed potatoes for comparison. The squash was a paler color and was somehow creamier than the potatoes even though the butter content was about the same. Unreal. I'm planting every seed left in my packet and growing them out so I can have them as little treats for the rest of the year.
These plants were the first thing in my garden to get powdery mildew, though, so make sure you're careful about airflow.
