Tropical Times in the Conservatory - Plant of the day - Date Palm "Phoenix dactylifera"

A cold and blustery day in St. Paul!  As I stand in the North Garden, surrounded by tropical lushness, I’m surprised to see snow swirling in the gusty winds outside.  I'm surprised to see this because it wasn’t snowing when I came in this morning.  I guess I need to listen to the weather forecast more often.  Seeing the snow fly outside makes me feel grateful and happy to be inside the beautiful Como Conservatory.

Sunken Garden - overcast outside
I got to work with new volunteer today. She started in the North Garden.  We had a rich discussion about art, culture and the intersection of art and economics as perceived and cultivated in human society.  Very interesting to meet new people and find out about their backgrounds and interests.  This volunteer is new to the path of gardening and ethnobotany but is well on her way to becoming a knowledgeable MCC interpreter!

Lots of young kids here today.  I was able to point out some well-hidden bananas to a couple of very young kids.  Too bad they are hidden - visitors love to see fruiting plants that they can identify with! 

The flower show is as beautiful as ever.  There's always a gardener's talk about the flower show at 1pm, but that's when my shift ends and I always need to go home to tend to my kiddies.  One day, I'm going to attend this talk!

Common Fig - Pollard Trimming
Today, a visitor asked about the difference between a date and a fig.  From a distance, both can seem to be much alike.  We talked about the fact that the date comes from the date palm and the fig from the fig tree.  Dates grow in bunches while figs grow singularly.  The date has a pit.  The fig has seeds inside.  They both provide fiber, but the fig more so and can detrimentally affect your health if you eat too much at once. 
Date Palm

The Plant of the Day is the Date Palm – Phoenix dactylifera.  Dates from the date palm are eaten the world over.  They are economically important to many regions in multiple countries.  The Date Palm offers many other economically and environmentally important features.  The entire date palm tree is very popular for landscaping.  Date seeds can be roasted and used to make coffee.  The seeds can be gound and turned into animal feed.  The seed oils, rich in several fatty acids, have been used in soaps and cosmetics.  Although small in size, the seed can be burnt and used as an effective charcoal.

The date palm trunk can be used in small scale construction or to make small items like fence posts.  As it grows, leaves fall off leaving a scar mark around the trunk. The inside of the trunk is filled with pith – a soft fiber material. Because of this, palms do not add growth rings each year to show their age.

Learning From Our Visitors. Plant of the Day: Ti Plant – "Cordyline terminalis"

The high number of visitors to the Conservatory continue to amaze me.  It’s great to see everyone here!  The nice aspect of having many visitors is that there are more people to talk with about the Conservatory collection.  I'm always impressed with the folks visiting the Conservatory because they always have a smile on their face and a 'hello' ready to share.

Calathea Plant - in the Palm Dome
I met a very nice visitor today named Dave.  We talked about the plant collection in the North Garden and then walked into the Palm Dome to identify a beautiful Calathea floor cover plant that does not have a name label. What is your favorite plant app?  I’d like to learn more about what apps that are used by gardeners and botanists!
Dave told me about an app named "Garden Answers" that will help identify a plant species using a picture (taken by your cell phone) of the plant's leaf. 

In addition to the cell phone apps, another good source of information for what's going on with the Conservatory plant collections is the Conservatory Gardner's Blog located at http://www.comozooconservatory.org/blogs/gardener-blogs/

Fig Tree
The large Fig tree in the North Garden has been pruned via a 'pollard' process to prune the top small branches.  They will grow back and eventually the foliage will be as beautiful as ever!

The plant of the day is the Ti (pronounced 'tea') plant - Cordyline terminalis – also known as the Hawaiian good luck plant!  This lovely plant is a member of the Lily family (Liliaceae).  This plant is found on many Polynesian islands and in the South Pacific.  Early Polynesians believed the Ti plant had divine power. To bring good luck and to dispel evil, fresh leaves were hung around dwellings, worn around the neck, waist, and ankles, and planted around homes.   
Ti Plant
Leaves can be different colors depending on the cultivar.  One really cool use for the Ti plant is to make Hawaiian hula dancer skirts and ceremonial neck ornaments and other decorations for the high ranking chiefs and other tribe members.  The long leaves have been used as food wrappers, plates, cups, table coverings, rain capes, thatch, clothes, hula skirts, sandals, and braided into leis.  The leaves have also been used to create beverages to fight diarrhea, to feed livestock, make fiber and cloth, store food and to thatch roofs.  These plants are grown as both house plants and are used in yards for landscaping.
